How to delete existing configuration on a 501 PIX

I was given a 510 PIX Ver 6.3(1)to reconfigure but have no information on the existing configuration and need to wipe it clean and start over how can I do this to get back to the factory default settings. I have tried the "monitor>" but I don't know the IP address of the PIX interface.and am not sure how to do the setup for recovering the password.

I think you are misunderstanding the procedure. When you go to monitor mode, you SET the IP address of the inside interface to whatever you want, set the IP address of the tftp server, set the name of the password recovery file on the tftp server. You then initiate a tftp transfer of the file and bingo.... you get a prompt asking if you want to erase the passwords. Works a treat.

I am pretty new at this and I am not sure do I use a direct straight through cable or crossover? I have tried both. But every time I ping I get no response to the address on the computer (tftp server). I must not be doing something right!
